H3/QUIC or HTTP/3 is the upcoming HTTP (Hypertext Transport Protocol) version that leverages QUIC.

H3/QUIC or HTTP/3 is a new standard in development that will affect how web browsers and servers communicate, with significant upgrades for user experience, including performance, reliability, and security.

HTTP is an essential backbone of the Internet — it dictates how communications platforms and devices exchange information and fetch resources. In short, it is what allows users to load websites.

An important difference in H3/QUIC HTTP/3 is that it runs on QUIC, a new transport protocol. QUIC is designed for mobile-heavy Internet usage in which people carry smartphones that constantly switch from one network to another as they move about their day. This was not the case when the first Internet protocols were developed: devices were less portable and did not switch networks very often. Check now H3/QUIC Check

H3/QUIC – HTTP/3 and QUIC are now available

We are happy to inform that all of our customers may now implement H3/QUIC – HTTP/3 with QUIC at no additional cost.

By enabling quicker response times, better network performance, and built-in encryption with TLS 1.3, support for HTTP/3 on our edge cloud network enables users to offer end users a better digital experience, particularly those using mobile devices or in regions of the world with spotty internet service.

The use of QUIC means that HTTP/3 relies on the User Datagram Protocol (UDP), not the Transmission Control Protocol (TCP). Switching to UDP will enable faster connections and faster user experience when browsing online.

The QUIC protocol was developed by Google in 2012 and was adopted by the Internet Engineering Task Force (IETF) — a vendor-neutral standards organization — as they started creating the new HTTP/3 standard. After consulting with experts around the world, the IETF has made a host of changes to develop their own version of QUIC.

H3/QUIC will help fix some of HTTP/2’s biggest shortcomings:

  • Developing a workaround for the sluggish performance when a smartphone switches from WiFi to cellular data (such as when leaving the house or office)
  • Lessening the impact of packet loss—when a single packet of data does not reach its destination, all other streams of data are no longer blocked—also known as “head-of-line blocking”
  • Faster connection establishment: QUIC enabled TLS version negotiation to occur concurrently with the cryptographic and transport handshakes
  • Clients can avoid the handshake requirement for servers they have already connected to using zero round-trip time (0-RTT) (the process of acknowledging and verifying each other to determine how they will communicate)
  • An enormous improvement over HTTP/2, QUIC’s new approach to handshakes will enable encryption by default and significantly reduce the danger of attacks
